Issue #1

All of my samples are loaded into a page via an IFRAME and a static html page. As a result, I had to change the following to target the new mime type.

Issue #2

Another place that a few of my samples imploded was situations where I was building up a Storyboard procedurally, and targeting a specific dependency property.  Beta 2 now uses a custom object called “PropertyPath”
Beta 1

Storyboard.SetTargetProperty(daX, "(ScaleX)");

Beta 2

Storyboard.SetTargetProperty(daX, new PropertyPath("(ScaleX)"));

Issue #3

A third place that caused an issue was the setting of a value for a Dependency Property. In Beta 1 I was forced to convert the value to a string regardless of the properties data type. Beta 2 now enforces strong data typing at execution time (Compiling had no issue since “SetValue” takes an object)

Beta 1

tile.SetValue(Grid.ColumnProperty, col.ToString());

Beta 2

tile.SetValue(Grid.ColumnProperty, col);
